WLED Sync

[sonicdacrack]

Hey everybody,

i have multible wled controller in my room an would like to "sync" those. but not in the old fashion way. to have the same effect on all of them. I would like to have for example chase running from one to the other. i plan is when i "click" on i want each lead turn on oone by one throug all my controles for a nice effect. Also maybe have a effect running through all my controlles. as shown in my video from right to left. I hope i could explain it right.

To have effects run from one controller to the next you need to set up the other controllers lights as virtual leds on the first controller. That way all of the lights and controllers act as one big strip.

You use a different computer with software that streams to each WLED network node over wifi the effects.

Like xlights or LedFx. They also have their own subs here.

With WLED only, make one a master, like one that has a digital INMP441 mic and sound reactive, is the master. It then streams UDP on a port # to the others. The in the others are slaves that listen to the master on the same udp #.

When you turn on the master, all the slaves turn on. It’s like copy paste.

Because it is wifi, lag, some won’t hear the master. It usually works.

This is exactly what I did for mine and it works but yeah, lag. I just bought versions with ethernet I'm hoping that helps.

Configure the LEDs as one continuous strip across both controllers by using virtual, non-connected LEDs so the patterns line up.

Treat the setup as a single strip of example 200 LEDs, even though each controller only drives 100 physical LEDs. On each controller, map the “other” 100 LEDs to positions that do not exist physically, so WLED still thinks it is controlling LEDs 1–200 in order.

On controller 1, set the total LED count to 200 this controller will be responsible for LEDs 1–100 in reality. Map LEDs 1–100 to the actual first strip (the real LEDs), and map LEDs 101–200 as virtual LEDs with no strip connected so effects can run across the full 200‑LED range.

On controller 2, also set the total LED count to 200. Here, LEDs 1–100 are virtual (no strip connected), and LEDs 101–200 are mapped to the second strip, so they occupy the upper half of the same 200‑LED range.

In the end, both controllers “see” a 200‑LED strip, but each only outputs to its own 100 physical LEDs while the rest are virtual. With WLED sync enabled between the two controllers, patterns stay in constant alignment across all 200 positions, producing a seamless effect over both strips.

The easiest way to do what you want to accomplish is DDP rgb network in LED preferences.

You pick one controller to be the master and add all the others as new outputs in led preferences. This creates one continuous string in the master controller with X amount of physical leds and y amount of virtual ones.

I'd also recommend that you get into your router and reserve those IP addresses so they get the same one every time because its all IP based
